Iraq
Iraqi MT-LB converted into a SPAAG armed with a ZU-23-2 anti-aircraft gun.
Iraqi MT-LBV fitted with wider tracks.
 
    MT-LBV fitted with wider tracks.
    MT-LB converted into a SPAAG by mounting a ZU-23-2 23 mm twin anti-aircraft gun on the rear part of the vehicle. The gun had its wheels removed and as such cannot be easily dismounted and used separately. There were at least two variations of this conversion; one with the ZU-23-2 mounted in an open-topped turret, the other with the ZU-23-2 mounted on a platform extending beyond the hull of the MT-LB with a roof for the gun operators. The second version was most likely intended to be used in a fire support role, as the roof would hinder the gun's sights at high elevation.[12]
